THE ROLE OF COMPANION ANIMALS IN SPREADING COVID-19.

Objective: In the twenty-first century, despite the development in infection management, and improvement of vaccines and therapeutic agents in the field of health, new viral outbreaks that can still be fatal in humans and animals are emerging. The infection of zoonosis COVID-19 from bat origin, the intermediate host of which is still being unclear, has appeared in people who visited animal bazaar in December 2019, in Wuhan, China. The World Health Organization declared this infection a pandemic in February 2020. Millions of people have been affected by this pandemic. The fight against the pandemic has had a great economic cost and continues to do so. Even people have changed their lifestyle. In this context, there have been concerns about companion animals with COVID-19 transmission, from human to animal or animal to human. The purpose of this review was to examine the studies on the presence and transmission of COVID-19 in companion animals such as cats, dogs, hamsters and horses. Result and Discussion: It has been reported in studies that most of the companion animals (cat, dog and hamster) were susceptible to SARS-CoV-2, and humans could be a source of infection for them. However, the potential role of companion animals in transmission to humans is not fully known. It is clear from this pandemic that the necessity of epidemiological investigation of infectious agents, especially zoonotic ones, in one health concept has emerged once again.Copyright © 2022 University of Ankara.

Clinical and epidemiologic features of SARS-CoV-2 in dogs and cats compiled through national surveillance in the United States

OBJECTIVE: To characterize clinical and epidemiologic features of SARS-CoV-2 in companion animals detected through both passive and active surveillance in the US. ANIMALS: 204 companion animals (109 cats, 95 dogs) across 33 states with confirmed SARS-CoV-2 infections between March 2020 and December 2021. PROCEDURES: Public health officials, animal health officials, and academic researchers investigating zoonotic SARS-CoV-2 transmission events reported clinical, laboratory, and epidemiologic information through a standardized One Health surveillance process developed by the CDC and partners. RESULTS: Among dogs and cats identified through passive surveillance, 94% (n = 87) had reported exposure to a person with COVlD-19 before infection. Clinical signs of illness were present in 74% of pets identified through passive surveillance and 27% of pets identified through active surveillance. Duration of illness in pets averaged 15 days in cats and 12 days in dogs. The average time between human and pet onset of illness was 10 days. Viral nucleic acid was first detected at 3 days after exposure in both cats and dogs. Antibodies were detected starting 5 days after exposure, and titers were highest at 9 days in cats and 14 days in dogs. CLINICAL RELEVANCE: Results of the present study supported that cats and dogs primarily become infected with SARS-CoV-2 following expo- sure to a person with COVID-19, most often their owners. Case investigation and surveillance that include both people and animals are necessary to understand transmission dynamics and viral evolution of zoonotic diseases like SARS-CoV-2.

The animal keeping culture and the motivation of animal keepers in Hungary

Background: In the past few decades the animal keeping culture and habits have changed a lot internationally, some animals have become family members. The COVID-19 pandemic has created an unprecedented situation in the world, including Hungary. In many places, the quarantine period was associated with Isolation and, therefore, an increase in the number of companion animals. Objectives: Our aims were to (1) survey the animal keeping culture and habits, (2) examine the motivation of the owners and (3) explore the attitudes about adoption, neutering, breeding and the use of livestock animals in Hungary. Materials and Methods: Specialized surveys were conducted among 843 persons through social media and personal interviews from 20 June to 30 August 2021 by using a questionnaire including 16 questions. The chosen groups were compared with Fisher's Exact test and Chi-square test. Results and Discussion: 97.0% of the respondents regard their dog as a family member. Nearly 25% of the respondents do not wish to neuter their dogs, because they want to breed the dogs or they find it unnecessary. The primary reason for cat keepers not to neuter their pet is the financial issue. Animal keepers and women are significantly more likely to consider their animal as a family member (p < 0.001). Men, the elderly, people who live in the countryside and those who have only elementary education think that neutering is of less importance (p < 0.001). Non-animal keepers, elderly people and men think more negatively about adoption. Buying an animal from a breeder is more important to the younger age groups (p < 0.001) arid those who live in Budapest (p < 0.01). 42.3% of the respondents gave the lowest evaluation scores to the assessment of the livestock units. Women, people from younger age groups (p < 0.05) and those who have higher education (p < 0.001) think more negatively about the use of farm animals. Non-animal keepers, the elderly and people of lower education consider the livestock animals' emotional intelligence lower (p < 0.05). Men (p < 0.001), people over 65 years of age (p < 0.001) and of lower education (p < 0:01), and also non-animal keepers (p < 0.001) accept significantly easier the use of livestock animals.

Warm-blooded animal toxoplasmosis and its connection to COVID-19: a review

Toxoplasmosis is a zoonotic illness that spreads from animals to people. Toxoplasma gondii, a protozoan parasite that infects warm-blooded mammals, causes the sickness. Toxoplasmosis is a parasitic infection that causes abortion and death in animals. Cats are the parasite's sole sexual hosts, thus they're the only ones who can get it. Because cats are frequent pets, they are highly likely to come into touch with humans. As a result, the disease poses a risk to human health. The potential danger is influenced by the frequency of oocyst secretion and the level of contamination in the environment. Toxoplasmosis has serious consequences for both animal and human health, hence preventative actions should be taken to reduce the dangers. COVID-19 is affected by such methods as well. Toxoplasmosis is thought to increase immunological and immunosuppressive factors, which increases the chance of SARS-CoV-2 infection and the severity of the resulting COVID-19. Research into Toxoplasma gondii intermediate hosts might help understand COVID-19's dynamics and determine if the virus can be transferred from animals to humans. We explore what we know about Toxoplasma gondii infection as a human parasitosis and how it may alter the course of SARS-CoV-2 infection in this review study.

Incidence and sero-surveillance of feline viruses in Korean cats residing in Gyeonggi-do

Incidences of major feline viral diseases provide basic information for preventing viral disease in cats. Despite the growing interest in feline viral diseases, sero-surveillances have been lacking. In this study, we analyzed the diagnoses of feline viral diseases and conducted a sero surveillance of feline panleukopenia virus (FPV), feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), and feline infectious peritonitis virus (FIPV) in Korean cats. Of the 204 confirmed cases since 2015, the numbers of diagnoses for FPV, FIPV, FCV, feline influenza virus, and FHV-1 were 156, 32, 12, 3, and 1 case, respectively. In total, 200 sera, collected between 2019 and 2021, were screened for the presence of antibodies against FPV, 2 FCVs, FHV-1, and FIPV using a hemagglutination inhibition test and a virus-neutralizing assay (VNA). The overall seropositive rates in cats tested for FPV, the 2 FCVs, FHV-1, and FIPV were 92.5%. 42.0%, 37.0%, 52.0%, and 14.0%, respectively. A low correlation (r = 0.466) was detected between the VNA titers of 2 FCV strains. The highest incidence and seropositive rate of FPV reveal that FPV is circulating in Korean cats. The low r-value between 2 FCVs suggests that a new feline vaccine containing the 2 kinds of FCVs is required.

Coinfection in the cases of feline panleukopenia: a literature review

Coinfection caused by bacteria, parasites, or viruses complicates almost all feline panleukopenia virus (FPV) infections. Pathogens that colonize the gastrointestinal tract, Clostridium perfingens, Clostridium piliforme, Cryptosporidium spp, Giardia spp, Tritrichomonas fetus, canine parvovirus type 2,Salmonella sp., feline coronavirus, feline bocavirus, and feline astrovirus were isolated in the presence of FPV infection. Complex mechanisms between viruses, bacteria, protozoa, and hosts contribute to the pathogenesis and severity of coinfection. Prompt and accurate diagnosis, vaccination precautions, and appropriate treatment play important roles in reducing morbidity and mortality. This article outlines the etiology, pathogenesis, diagnosis, prevention, and treatment that can help veterinarians and pet owners improve their knowledge of managing the diseases.

Restrospective study of hemogram profile in effusive feline infectious peritonitis

Feline Infectious Peritonitis (FIP) is highly mortality disease in cats. The reliable and fast diagnosis is crucial to the best prognosis. The aim of this study to evaluate the hemogram profile in cats infected with effusive FIP. Twenty cats had been diagnosed effusive FIP at Animal Clinic Department of Internal Medicine, Faculty Veterinary Medicine, Universitas Gadjah Mada were used in the study. The diagnosis were based on clinical examination, ultrasound, x-ray, rivalta test, and rapid test. The hemogram profile were analyzed include routine hematology and serum biochemistry. Hemogram profile in effusive FIP showed the decreased hematocrit, hyperproteinemia, and leukocytosis with an average 22.9+or-7.4%;9.0+or-2.2 g/dL;22425+or-4116 cells/mm3 respectively. Erythrocyte, hemoglobin and fibrinogen levels were still in the normal range. The results of differential leukocytes revealed that 90% cats had neutrophilia and 75% lymphopenia with an average 20066+or-3337 cells/mm3 and 1861+or-1818 cells/mm3 respectively. The blood chemistry profile showed 60% of cats experienced increase in SGPT and SGOT with an average 138.4+or-72.3 IU/L and 101+or-60.5 IU/L respectively. Hyperglobulinemia was found in 90% samples with an average 6.7+or-0.8 g/dL. All cats have a low albumin:globulin ratio with an average 0.3+or-0.1. The hemogram profile of effusive FIP were: leukocytosis, neutrophilia, lymphopenia, hyperglobulinemia, and decreased albumin-globulin ratio..

The role of regular engagement with non-companion animals and proximity to green and blue space for mental health, wellbeing, and loneliness during Covid-19 social-distancing measures: findings from a UK survey study

Context. The Covid-19 pandemic led to increased use of green/blue space as indoor spaces became frequently inaccessible. These changes affected the direct interactions between humans and nature. Aims. To investigate the links between mental health, loneliness, wellbeing, and interaction with non-companion animals, proximity to and use of green/blue space. Methods. A cross-sectional online survey of adult UK residents was conducted between April and June 2020. The questionnaire included validated and bespoke items measuring demographics and exposures and outcomes related to mental health, wellbeing, loneliness, human-animal interactions with non-companion animals (wildlife/farm animals), and proximity to and use of green/blue space before and since the first UK Covid-19 lockdown. Key results. Of 5926 participants, 4408 (74.4%) reported interacting with non-companion animals at least every other day. Frequent engagement with non-companion animals was significantly associated with smaller decreases in mental health scores (b = 0.131, 95% CI [0.007-0.256], P = 0.038) and smaller increases in loneliness scores (b = -0.135, 95% CI [-0.241-0.030], P = 0.012). Just under half (48.4%, n = 2867) reported living directly next to a green/blue space, and over half (52.3%;n = 3097) reported using such space at least every day since lockdown. Regular use of green/blue space since lockdown was significantly associated with higher mental health (b = 0.154, 95% CI [0.037-0.272], P = 0.010), lower loneliness (b = -0.334, 95% CI [-0.430 - -0.238], P = 0.001), and higher wellbeing (b = 0.810, 95% CI [0.572-1.047], P = 0.001). Closer proximity to such space was significantly associated with lower loneliness scores (b = -0.224, 95% CI [-0.319 - -0.130], P = 0.001), and higher wellbeing scores (b = 0.632, 95% CI [0.391-0.873], P = 0.001). Conclusion. The multi-faceted human-nature relationship may promote key human health benefits in the context of the lockdown. Implications. These findings have highlighted the importance of green/blue space and the human-animal relationship, and how they might play a critical role in maintaining people's mental health within a pandemic context. Further targeted investigations relating to these areas and links with human health are important within both pandemic and non-pandemic contexts.

SARS-CoV-2 Infection and Clinical Signs in Cats and Dogs from Confirmed Positive Households in Germany.

On a global scale, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a serious threat to the health of the human population. Not only humans can be infected, but also their companion animals. The antibody status of 115 cats and 170 dogs, originating from 177 German households known to have been SARS-CoV-2 positive, was determined by enzyme-linked immunosorbent assay (ELISA), and the results were combined with information gathered from a questionnaire that was completed by the owner(s) of the animals. The true seroprevalences of SARS-CoV-2 among cats and dogs were 42.5% (95% CI 33.5-51.9) and 56.8% (95% CI 49.1-64.4), respectively. In a multivariable logistic regression accounting for data clustered in households, for cats, the number of infected humans in the household and an above-average contact intensity turned out to be significant risk factors; contact with humans outside the household was a protective factor. For dogs, on the contrary, contact outside the household was a risk factor, and reduced contact, once the human infection was known, was a significant protective factor. No significant association was found between reported clinical signs in animals and their antibody status, and no spatial clustering of positive test results was identified.

Impacts of the COVID-19 pandemic on antimicrobial use in companion animals in an academic veterinary hospital in North Carolina.

Antimicrobial resistance (AMR) in bacterial pathogens reduces the effectiveness of these drugs in both human and veterinary medicine, making judicious antimicrobial use (AMU) an important strategy for its control. The COVID-19 pandemic modified operations in both human and veterinary healthcare delivery, potentially impacting AMU. The goal of this research is to quantify how antimicrobial drug prescribing practices for companion animals in an academic veterinary hospital changed during the pandemic. A retrospective study was performed using prescribing data for dogs and cats collected from the NC State College of Veterinary Medicine (NCSU-CVM) pharmacy, which included prescriptions from both the specialty referral hospital and primary care services. Records (n = 31,769) for 34 antimicrobial drugs from 2019-2020-before and during the pandemic-related measures at the NCSU-CVM-were compared. The prescribed antimicrobials' importance was categorized using the FDA's Guidance for Industry (GFI #152), classifying drugs according to medical importance in humans. A proportional odds model was used to estimate the probability of more important antimicrobials being administered in patients seen during the pandemic versus before (i.e., critically important vs. highly important vs. important). Rates of AMU per week and per patient visit were also compared. During the pandemic, cumulative antimicrobials prescribed per week were significantly decreased in most services for dogs. Weekly rates for Highly Important antimicrobials were also significantly lower in dogs. For important and critically important antimicrobials, rates per week were significantly decreased in various services overall. Rates of antimicrobial administration per patient visit were significantly increased for Highly Important drugs. Patients in the internal medicine, dermatology, and surgery services received significantly more important antimicrobials during the pandemic than before, while cardiology patients received significantly less. These results suggest that the pandemic significantly impacted prescribing practices of antimicrobials for companion animals in this study.

Family Bonds with Pets and Mental Health during COVID-19 in Australia: A Complex Picture.

The COVID-19 pandemic has drawn attention to the health-promoting features of human-animal relationships, particularly for families with children. Despite this, the World Health Organization's (1986) Ottawa Charter remains human-centric. Given the reciprocal health impacts of human-animal relationships, this paper aims to (i) describe perceived pet-related benefits, worries, and family activities; and to (ii) examine differences in perceived benefits, worries, and activities for parents and children with and without clinical mental health symptoms. We recruited 1034 Australian parents with a child < 18 years and a cat or dog via a national online survey between July and October 2020. Most parents reported their pet was helpful for their own (78%) and their child's mental health (80%). Adjusted logistic regression revealed parents with clinical psychological distress were 2.5 times more likely to be worried about their pet's care, well-being, and behaviour (OR = 2.56, p < 0.001). Clinically anxious children were almost twice as likely to live in a family who engages frequently in pet-related activities (e.g., cooked treats, taught tricks, OR = 1.82, p < 0.01). Mental health and perceived benefits of having a pet were not strongly associated. Data support re-framing the Ottawa Charter to encompass human-animal relationships, which is an often-neglected aspect of a socioecological approach to health.

Identification of feline corona- virus in breeding catteries by molecular biological methods and shedding persistency

Infectious peritonitis virus (FIPV) causes a fatal disease in cats. This virus occurs both in cats bred in households with optimal welfare and outdoor cats. Feline patients with the effusive form of disease usually survive a few days to weeks from the appearance of the first clinical signs. Cats with the non- effusive form survive for weeks to months. FIPV is caused by a mutation from feline enteric coronavirus (FECV). In our study, we diagnosed feline coronavirus from the feces of 82% of the tested cats. The persistence of the feline coronavirus in the organism is influenced by environmental factors, the genome of the host and the causative agent. Negative environmental conditions that increase the likelihood of FIPV disease are long-term stress, mainly more labile individuals and a high concentration of domesticated cats in one place. In the host, there are important factors such as immune system performance, age, breed and genetic background. In our study, we primarily verified the real time RT-PCR method for identifying the virus from the feces of 71 cats and subsequently gaine the valuable data on the dynamics of feline coronavirus excretion, primarily for epizootological purposes and for the purposes of genetic analyzes of susceptibility to infection.

Possession of exotic animals and zoonotic diseases: an approach from the Mexican context

The possession of exotic animals as pets is a social practice that has become more visible in Mexico in recent years, so it is interesting to understand its environmental and social implications and those related to human health. The present study aims to identify the main species of exotic animals kept as pets and the zoonotic diseases reported in these species. We analyzed official figures of seizures of exotic fauna in Mexico and reviewed specialized literature on zoonotic diseases documented in Mexico in these species. We identified zoonoses in species of fauna that can be acquired legally and illegally in the country, reported in environments in which animals coexist with other species and are in direct contact with people, which represents an important factor in the spread and propensity of this type of disease. We conclude that the sanitary regulation of wildlife markets, the monitoring and studying microorganisms associated with wildlife are valuable strategies to prevent the emergence of zoonoses.

Truncated expression of S1 protein of Feline infectious peritonitis virus and preparation of its monoclonal antibody

In order to develop monoclonal antibody against Feline infectious peritonitis virus (FIPV) S1 protein, the truncated S1 protein (rS1) was expressed through Escherichia coli and subsequently purified. Then BALB/c mice were immunized with purified rSl. Three hybridoma cell strains, named 2D7,3D8 and 5G1, stably secreting antibodies against rSl were obtained by cell fusion and indirect ELISA screening. The identification of antibody subtype showed that antibody subtypes of 2D7,5G1 and 3d8 strains were IgG2a,IgG2a and IgGl,respectively. And the light chain of those three hybridoma cell strains was Kappa. Result of karyotype identification of hybridoma cells showed that the chromosome numbers of those three hybridoma cells were about 102,101 and 103, which was belonged to the karyotype of hybridoma. The titer of ascites antibody for indirect ELISA was 1 : 204 800, and monoclonal antibodies were purified. Moreover, all of 2D7,3D8 and 5G1 could react with rS1 by Western-blot and FIPV in cells by IFA. These data suggest that three monoclonal antibodies against rSl with good activities were ideal materials in the study of early diagnosis of FIPV and the biological function of FIPV in the future.

Impact of COVID-19 on the productivity of ornamental fish farmers: a case of ornamental fish farms in Colombo district in Sri Lanka

Ornamental fish production in Sri Lanka has become a valuable foreign exchange earner during recent past years. However, COVID-19 pandemic has been explored worldwide and it has affected the world trade and economy from different perspectives. This study was conducted to explore the impact of the COVID-19 pandemic on ornamental fish production., Moreover, study on present status of ornamental fish farmers' major constraints and suggestions to overcome those constraints of ornamental fish farmers were also conducted. In Colombo district, four important Divisional Secretariat (DS) divisions were purposely selected for the study, as they are the main ornamental fish production areas of the district. The data was collected from a randomly selected 60 farmers using a field survey from July to October 2020. Descriptive statistics, two sample Wilcoxon signed-rank test and chi-square test were used to analyses the data. Results revealed that, there are both negative and positive impacts on ornamental fish production due to the COVID-19 pandemic. Ornamental fish farmers have to face mainly production and marketing problems. Some of them have engaged in coping strategies and resilience methods during COVID-19 period. Coping strategies have shown a significant association with the income and the production capacity of the farms. However, the majority of ornamental fish farmers haven't engaged in resilience methods during the COVID-19 pandemic. Other than the COVID-19 pandemic, the major constraints of ornamental fish production were lack of market information about the changes in the overseas markets and demand, the low price given for the product and lack of communication between farmers and exporters. Ideal "ORNAFISBIZ" model is suggested for overcome those constraints in order to protect the ornamental fish farmers in this area.

Differentiating infectious from non-infectious respiratory disease in the cat and dog

This paper describes the clinical signs and use of differential laboratory diagnostic techniques (computed tomography, cytology, histopathology, antigen/antibody detection and polymerase chain reaction) for infectious (viral, bacterial, fungal and parasitic) and non-infectious (inflammatory/immune mediated, neoplastic, cardiac, malformation, foreign body, smoke inhalation, aspiration of caustic material, non-cardiogenic, pulmonary oedema, traumativ, pneumothorax, pulmonary contusions and idiopathic) causes of respiratory diseases in cats and dogs in Ontario, Canada.

Brachycephalic obstructive airway syndrome: an overview

One of the conformational issues by the explosion Of pet ownership throughout the COVID 19 pandemic is the Ming number dunes of brachycephalic obstructive envay syndrome (BOAS), which is a condition prevalent in some of the UK's most copular dog breeds The challenges the veterinary profession is not only to identify and treat affected individuals from within the population of dogs presenting to primary care clinicians, using surgical and non-surgical options but also to educate clients on how to recognise clinical signs of the disease as early as possible.

Effectiveness of rapid immunochromatographic tests to the detection of feline Coronavirus

Feline coronavirus (FCoV) belongs among pathogens with common occurrence in the cats population in the whole world. FCoV is ubiquitous in environments with a higher concentration of cats, e.g. in shelters, multicat households and kennels. FCoV primarily attacks the digestive feline tract, replicates in its cells and is excreted in the feces to surroundings of permanently or transiently infected cats. The aim of the study was the detection of FCoV in the feces of newly admitted cats to the shelter by the qPCR method and by means of commercial rapid immunochromatographic (antigen) tests from three different producers. For each of the antigen tests, sensitivity and specifity were determined by comparison with the qPCR analysis result. Out of 70 examined fecal samples, viral RNA was by the qPCR analysis identified in 44 samples (62.9%). Neither the age nor the gender of cats played a significant role in the viral excretion. Found sensitivity of the antigen tests was at a low (< 35%;tests A and C) to a satisfactory level (> 50%, test B). The number of viral particles in the samples determined by the qPCR method did not correlate significantly with the result of the antigen tests. The results of this study suggest that the use of rapid antigen tests for routine screening of FCoV shedding in feline shelters is limited due to the high rate of false-negative results.
